[PATCH v7 0/5] media: mediatek: support mdp3 on mt8183 platform

From: Moudy Ho
Date: Tue Aug 24 2021 - 06:00:44 EST


Changes since v6:
- Refactor GCE event to corresponding node.
- Fix dt_binding_check fail.
- Fix compilation errors.

Changes since v5:
- Rebase on v5.14-rc6.
- Move MMSYS/Mutex settings to corresponding driver.
- Revise the software license description and copyright.
- Remove unnecessary enum. or definitions.
- Optimize platform/chip definition conditions.
- Use general printing functions instead of MDP3 private ones.
- Fix compile warning.

Changes since v4:
- Rebase on v5.13-rc1.
- Remove the CMDQ flush flow to match the CMDQ API change.
- Integrate four of MDP's direct-link subcomponents into MDP controller node
from syscon node to avoid illegal clock usage.
- Rewrite dt-binding in a JSON compatible subset of YAML
- Fix a bit of macro argument precedence.

Changes since v3:
- Rebase on v5.9-rc1.
- modify code for review comment from Rob Herring, cancel multiple nodes using
same register base situation.
- control IOMMU port through pm runtime get/put to DMA components' device.
- SCP(VPU) driver revision.
- stop queuing jobs(remove flush_workqueue()) after mdp_m2m_release().
- add computation of plane address with data_offset.
- fix scale ratio check issue.
- add default v4l2_format setting.

Changes since v2:
- modify code for review comment from Tomasz Figa & Alexandre Courbot
- review comment from Rob Herring will offer code revision in v4, due to
it's related to device node modification, will need to modify code
architecture

Changes since v1:
- modify code for CMDQ v3 API support
- EC ipi cmd migration
- fix compliance test fail item (m2m cmd with -f) due to there is two problem in runing all format(-f) cmd:
1. out of memory before test complete
Due to capture buffer mmap (refcount + 1) after reqbuf but seems
no corresponding munmap called before device close.
There are total 12XX items(formats) in format test and each format
alloc 8 capture/output buffers.
2. unceasingly captureBufs() (randomly)
Seems the break statement didn't catch the count == 0 situation:
In v4l2-test-buffers.cpp, function: captureBufs()
...
count--;
if (!node->is_m2m && !count)
break;
Log is as attachment

I will paste the test result with problem part in another e-mail

Hi,

This is the first version of RFC patch for Media Data Path 3 (MDP3),
MDP3 is used for scaling and color format conversion.
support using GCE to write register in critical time limitation.
support V4L2 m2m device control.
